Increased opportunity for sexual conflict promotes harmful males with elevated courtship frequencies

Mating systems have a profound influence on the probability of conflict occurring between the sexes. Promiscuity is predicted to generate sexual conflict, thereby driving the evolution of male traits that harm females, whereas monogamy is expected to

Sexual selection theory makes clear predictions regarding male spermatogenic investment. To test these predictions we used experimental sexual selection in Drosophila pseudoobscura, a sperm heteromorphic species in which males produce both fertile an

Understanding the processes underlying the origin of new species is a fundamental problem in evolutionary research. Whilst it has long been recognised that closely related taxa often differ markedly in reproductive characteristics, only relatively re

Sexual conflict has been predicted to drive reproductive isolation by generating arbitrary but rapid coevolutionary changes in reproductive traits among allopatric populations. A testable prediction of this proposal is that allopatric populations exp

Our expectations for the evolution of chemical signals in response to sexual selection are uncertain. How are chemical signals elaborated? Does sexual selection result in complexity of the composition or in altered quantities of expression? We addres

Sexual conflict over reproduction can occur between males and females. In several naturally promiscuous insect species, experimental evolution studies that have enforced monogamy found evidence for sexual conflict. Here, we subjected the naturally pr

Courtship song serves as a sexual signal and may contribute to reproductive isolation between closely related species. Using lines of Drosophila pseudoobscura experimentally selected under different sexual selection regimes, we tested whether increas

The battle of the sexes takes a sinister turn in the bean weevil. Because the costs and benefits of polygamy differ for males and females, copulation is not always a cooperative venture between the sexes1. Sperm competition2 can build on this asymmet
